Fault Indications

This amplifier uses a comprehensive fault sensing system to self-diagnose all critical operating areas, protect
itself against faults and report fault conditions. The two main areas of fault are non-shutdown faults, and
faults for which the amplifier must shut itself down.
Non-shutdown faults are non-critical faults, during which the amplifier can continue to operate for the rest
of the listening session, but which should be attended to as soon as possible at the end of the listening
session.
Critical shutdown faults are those which, if not attended to immediately could damage the amplifier, and they
are divided into three main groups:- Tube red, Heat and Power.
